20a2143661e360b3faa5b11b339f509a_0 | IBM Recommended values for web server plug-in config - United States TECHNOTE (FAQ)
QUESTION
In the web server plug-in, what do the LoadBalanceWeight, MaxConnections, ConnectTimeout, ServerIOTimeout, RetryInterval, IgnoreAffinityRequests, and GetDWLMTable options mean and what are the recommended settings for these ... |
20a2143661e360b3faa5b11b339f509a_1 | LoadBalanceWeight is a starting "weight". The value is dynamically changed by the plug-in during runtime. The "weight" of a server (or clone) is lowered each time a request is assigned to that clone. When all weights for all servers drop to 0 or below, the plug-in has to readjust all of the weights so that they are abo... |
20a2143661e360b3faa5b11b339f509a_2 | Note: At runtime, the LoadBalanceWeight of each appserver in a cluster are normalized by their highest common factor. For example, 100, 90, 80 have a common factor of 10. So, these configured weights would be divided by 10 at runtime, resulting in actual starting weights of only 10, 9, 8. Setting all clones to the same... |
20a2143661e360b3faa5b11b339f509a_3 | MaxConnections is used to gauge when a server is "starting to become overwhelmed". It is not used to determine when to fail-over (mark the server "down"). When a request is sent from the plug-in to the WAS appserver, it is called a "PendingRequest", until the response comes back. If the application running in WebSphere... |
20a2143661e360b3faa5b11b339f509a_4 | quickly the application and appserver respond to each request. If normal responses are returned in less than one second, it may be appropriate to set a low value for MaxConnections, like 20 or so. However, if it normally takes several seconds to get a response from the application, then it would be prudent to use a hig... |
20a2143661e360b3faa5b11b339f509a_5 | Recommended value = 20 - 100 depending on application response times |
20a2143661e360b3faa5b11b339f509a_6 | *Best Practices: with MaxConnections="-1" use LogLevel="Stats" to monitor the pendingRequests numbers in the plug-in log, under normal conditions. Then, choose a value for MaxConnections that is significantly higher than the highest number shown in the log. This method will help you to determine a MaxConnections value ... |
20a2143661e360b3faa5b11b339f509a_7 | ServerIOTimeout means "how long should the plug-in wait for a response from the application". After the socket is opened, the plug-in sends the request to the Application Server. The application processes the request and a response is sent back to the client, through the plug-in. How long should that take? What is reas... |
20a2143661e360b3faa5b11b339f509a_8 | On the other hand, a negative value means that the plug-in WILL mark the appserver down after a ServerIOTimeout pops. So, if you want the plug-in to immediately mark the appserver down and fail-over to another appserver in the same cluster, use a negative value. |
20a2143661e360b3faa5b11b339f509a_9 | Recommended value = -900 (that is negative 900) |
20a2143661e360b3faa5b11b339f509a_10 | Note: The ability to use a negative ServerIOTimeout value was introduced in plug-in apar PK72097 [http://www-01.ibm.com/support/docview.wss?uid=swg1PK72097].
*Best Practices: use traces to determine the amount of time it takes for your application to respond to requests under normal conditions. Be sure to include the ... |
20a2143661e360b3faa5b11b339f509a_11 | ServerIOTimeoutRetry can be used to decrease the number of retries after ServerIOTimeout has fired. By default, the Plug-in will try a request equal to the number of members in the cluster. For example, if the cluster has four members, and there is a ServerIOTimeout, the Plug-in will try it a second time. If the retry ... |
20a2143661e360b3faa5b11b339f509a_12 | RetryInterval is the time that the plug-in will wait before trying again to use an appserver that was marked down. The optimal value for RetryInterval depends on the number of appservers in the cluster, and the value used for ServerIOTimeout. You can use the following formula to determine the maximum RetryInterval valu... |
20a2143661e360b3faa5b11b339f509a_13 | Warning: Setting RetryInterval to a value higher than the recommended maximum, based on the formula above, can lead to an undesirable situation where all of the appservers in the cluster may be marked down simultaneously resulting in all requests temporarily failing.
Recommended value = 60 (this is the default)
Affin... |
20a2143661e360b3faa5b11b339f509a_14 | In the plug-in config there is a property called IgnoreAffinityRequests. This property determines if affinity requests will affect the load balance weights, or not. The default value for IgnoreAffinityRequests is True, which means that affinity requests will not have any affect on the load balance weights. This is best... |
20a2143661e360b3faa5b11b339f509a_15 | Fail-over occurs when the plug-in marks a cluster member appserver (or clone) as "down", and then sends the pending requests to other members of the same cluster. This can happen if the plug-in is unable to open a new connection to the appserver within the ConnectTimeout. Or fail-over can happen if the plug-in has alre... |
20a2143661e360b3faa5b11b339f509a_16 | send any requests to it. After RetryInterval the plug-in will check to see if that appserver can be used successfully again. If so, the "down" flag will be removed and the appserver will be used again. |
20a2143661e360b3faa5b11b339f509a_17 | Note: By default, the number of attempts to handle a request is limited by the number of appservers in the cluster. For example, if there are only two appservers in the cluster, and the request fails once, the plug-in will only attempt that request one more time (total of two attempts). Or another example, if there are... |
20a2143661e360b3faa5b11b339f509a_18 | If Memory-to-Memory (M2M) session replication is enabled in WebSphere Application Server, then the GetDWLMTable setting in the plug-in config must be changed to "true". Memory-to-Memory replication uses partition IDs rather than clone IDs. This can lead to broken session affinity if GetDWLMTable is set to false (which ... |
20a2143661e360b3faa5b11b339f509a_19 | Each web server child process loads a separate instance of the web server plug-in. And multiple running instances of the web server plug-in do not share information with each other. For example if the IBM HTTP Server web server is configured to start 3 child processes (StartServers 3), then there will be 3 instances of... |

20a2143661e360b3faa5b11b339f509a_21 | If you choose to use more than one web server child process, keep in mind that the plug-in settings are handled on a per instance basis. For example, MaxConnections means the number of pending requests that will be allowed on that server, for each plug-in instance. If MaxConnections = 20, and there are 3 web server chi... |
